" l 5 claims. (o1. 5;1) l ,s

Ay cable A13 is attached) to a rod 14 Carried by r:this invention relates to an attachment for a Yclay shingle making machine, the general object of the invention being to provide means fort automatically punching holes in the shingles Without waste of material as the clay member passes from the die to the cutting means.

This invention also consists in certain other features of construction and in the combination y and arrangement of the several parts, to be hereinaiter fully described, illustrated in the accompanying drawings and specically pointed out in the appended claims. 1 r

- vIn describingthe invention in detail', reference rwill be had to the accompanying drawings 'wherein like characters denote like or corresponding parts throughout the several views, and inwhich2 Figure 1 is aplan view showingportion of a shingle making machine, with our invention applied thereto. 1 f

Figure 2 is an elevation of Figure l. f

Figure 3 is asection on line 3--3 of l'1igure2.` y Figure 4 is a section on line 4 4 of Figure 2. Figure 5 is a bottom plan view of portionof` a carrier or pallet.

As is Well known, the forming mechanism of a clay shingle making machine forms the clay intoa rectangular member having two vertical partitions therein, with the four sides andthe two partitions, when separated, formingl six shingles. This member passes from the forming device or die upon the carriers or pallets 1 which carry thernember to cutting means which cuts the member into blocks, these blocks being-divided into the shingles, as before described. The pallets4 are connected to the endless chains 2 supported by the rolls 3 at theends of vthe table A,.only one of these rolls being shown.

In carrying out our-invention, we 'provide a frame B above the table A, `this frame consisting of two bars e fastened to the upright member 5 at the die end of the table and having their other endsconnected together by a cross piece/6. A member or block 7 is sldably arrangedon this frame by having holes therein through which the bars pass and the lower part of .the block is formed with an opening 8 through whichthe clay member passes. This member is shown at X in dotted linesin Figures land 2. A-shaft 9 is rotatably supported at the upper vpart'of the member or block '7l and has itsfends cranked, as at 10, one crank being longerthan the other and this long crank is adapted to engagethe 'bent end'of a post or upright 11 on the table when the block has been moved to a certain extent' the block '7 and passes over the guiding pulleys 15-v ony the member 5/and has aweight 16 attached toits other end,`this"weight acting to Vhold the block against the stop llon the frame B. `Thus it will be seen that as the pallets move along,`the posts or up'rights 2 on each pallet will 'strike the cranked ends 10 of the shaft 9 and thus causefthe block 7 to move with the pallet vuntilI the long crank '10' strikes the stationary upright 11,'` which causes the shaftto turn until `thecranked ends 10 pass abo-ve the posts oruprights 12, when the weight lvwill return'the block -'7 against the lstop 17, where it will be in Y position to be engaged by" the uprights of the 'next pallet, which move it forwardly, as before described.v 'A pair of 1 punch pins 18 is slidably arranged in each side of the'block and in the top, these pins projecting into the opening 8 when the pins are inoperative position so that vthey'will punch holes in the member X from the sides and top thereof and the side pins are made longfen'oughfso that they will Vextend through the yside'parts vaswell as they partitions of the clay member'. Eachset or" pins is fastened to a plate A19, the .topplate` being connected by a link 20V with a lever 21 pivotedfto the Stop of the block and the' 'side platesbeing connectedby the links 22 with the shafts23 passing throughY the block and each shaft' has an arm 2,4 thereon which is connectedby a llink 25to the lever 2l. Thislever has a Weight 25 thereon which tends 'to hold the lever in lowered 'position' with 'the pins in retracted positionbut ,when theileveris raised, the vconnections between the leversv and the plates 19 which carry the pins will project the pins into the opening 8 and thus vcause ythe plnsto 4perforate the clay member. As shown, the'block is formed with an extension 7 inwh'ich Vvthe pins arelocated, the extension being'of less Y varea'than the, blockjso that the levers and links can 'be pivoted tothe .mainpartof the block uto operatethe'pins carried'by :the extension.

, arm 27 is carried'by the frame B and an shaped lever 28 is .pivoted to the arm, with one portion oi the lever 23 .adapted torest on the warm'under-the action oi gravity.` ,ln this posi.- tion, the zlever is in an inclined position so that as the block'moves Yforwardly or with azpallet, Ya bent part 29 vof the lever k21 will vengage the lever 28-and ride up the same so that the weighted lever A21 is raised and thus i the pins' to be vprojected `into the clay member, .As the part 29 rides oil the upper end of the lever 27, the Weight r in position to again ride up the lever 28 on the forward movement of the block.

A double lever 30 is pivoted to the forward end of each pallet on the under side thereof, and has a pair of punch pins 31 at its other end which pass through holes in the pallet. A weight 32 on the lever 30 tends to hold the same in lowered position, with the pins ilush or substantially so with the top of the pallet. The table top is formed with an inclined part 33 which will engagel the double lever arrangement as the pallet moves forwardly so as to swing the double lever upwardly against the acti-on of its weight and thus project the pins 31 into the bottom of the clay member. As the pallet nears the other end of the table, it rides down a similar portion 33 so that the weighted levers can `drop and thus retract the pins. The parts are so positioned and arranged that the holes made by the punches or pins 18 in the block will register with those made in the bottom of the member by the pins 31.

Thus it will be seen that we have provided automatic means wherebyv a pair of holes will be punched in each shingle forming part of a clay member which is adapted to form six shingles when the parts are separated. These holes, of course, act to receive the nails which are used to fasten the shingles in place. It will, of course, be understood that the parts, wherever necessary or desirable, can be made adjustable and that springs or other means can be used instead of the weights and if desired, the block can be returned to its normal position by means operated by the pallets on the lower reach of the endless member.

The block may be provided with rollers or other anti-friction means which engage the parts of the frame B and a shock absorbing spring 17 may be provided for absorbing the shocks due to the block striking the stop means, this spring also tending to start the block on itsl return movement. Of course, a stop 17 and its spring may be placed on the other member of the frame B, if desired.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. n,

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within thel scope of the appended claims.
